what is the difference?

Question

case1: it works

function addNumbers(a,b){
var c = a+b;
return c;
}
document.write(addNumbers(5,6));

case2:but this doesn't work:

function addNumbers(a,b){
return a+b;
}
var c = addNumbers(5,6)

case3: again, this looks similar to the 2nd case bt it works:

function myFunction(a,b){
return a*b;
}
var c = myFunction(5,6);

i would like to know, why case2 doesn't give answer, as in case1...and what makes t be different from case3(not the sign of operation)

Answer 1

add a ; at end of var c

Answer 2

var c = addNumbers(5,6); as @Eldar said...the semicolon ; at the end of this expression was missing.... you didn't forget it for the other examples that's why they worked but not that one...

Answer 3

you have space between brackets and 5 in the 2nd example
